4.1  From the rate expression for the following reactions, determine their order of reaction and the dimensions of the rate constants.

         C_{2}H_{5}Cl(g\rightarrow )C_{2}H_{4}(g)+HCL(g) \: Rate=k\left [ C_{2}H_{5}Cl \right ]

so the order of the reaction is 1 and the dimension of k =                                           

4.1     From the rate expression for the following reactions, determine their order of reaction and the dimensions of the rate constants.

             CH_{3}CHO(g)\rightarrow CH_{4}(g)+CO(g)\: \: Rate=k\left [ CH_{3} CHO\right ]^{3/2}

Given  therefore the order of the reaction is 3/2 and the dimension of k                                       

4.1     From the rate expression for the following reactions determine their order of reaction and the dimensions of the rate constants.

         (ii)   H_{2}O_{2}(aq)+3I^{-}(aq)+2H^{+}\rightarrow 2H_{2}O(I)+I_{3}^{-}Rate=k\left [ H_{2}O_{2}\right ]\left [ I^{-} \right ]

Given rate =  therefore the order of the reaction is 2 Dimension of k =                           

4.1     From the rate expression for the following reactions, determine their order of reaction and the dimensions of the rate constants.

            3NO(g)\rightarrow N_{2}O\: \: Rate= k\left [ NO \right ]^{2}

Given pieces of information Rate =  so the order of the reaction is 2 The dimension of k =
